Robust automatic watch in diver's watch design for all weather conditions

Built to jump into the water with.

Thanks to stainless steel, a screw-down crown and sapphire crystal, our Marus can easily withstand dives up to 20 atm.

The mechanical automatic movement inside sets the pace, whether in the water or in everyday life.

Worry-free thanks to sapphire crystal

We only use sapphire crystal for our timepieces. This type of watch glass is usually found in the luxury watch market.

For a perfect view of the dial, we apply a double anti-reflective coating to the sapphire crystal.

What exactly is sapphire crystal?

Sapphire is the third hardest transparent material in the world - after diamond and moissanite.

Curved sapphire crystal not only looks good, it makes the durable watch crystal even more resistant.

This makes it virtually impossible for your sapphire crystal watch to get scratched in everyday life.

Resistant in water and on land

✓ Screw-down crown for ultimate water resistance up to 20 bar

✓ Fine ceramic bezel with rotating function

✓ Luminous hands and indices for optimal visibility, whether under water or at night

Mechanical movement for technology lovers

The vibrations of the rotor make the automatic movement run (without any batteries).

A special highlight: the second hand, driven by 21,600 A/h (half oscillations per hour), floats fluidly over the dial.

Hand-assembled and quality-tested several times by experienced watchmakers.

What our customers say about us

Why we make Bauhaus watches?

In your search for a classic and durable watch, you are faced with 2 alternatives today:

1. you can buy a watch from a luxury manufacturer for a very high price, or
2. a watch from a trendy brand whose quality is as short-lived as the trend that made the brand popular.

Moin! I'm Dustin Fontaine, Founder of STERNGLAS...

When I worked in a watch manufactory during my school days and was looking for a watch for myself, I realised that there would have to be a 3rd alternative.

3. Since 2016, we have been breaking new ground and developing timeless Bauhaus-style watches that will outlive trends and continue to give pleasure for many years to come. And all that at a fair price.

In the meantime, over 53,000 watch lovers are convinced of our mission and our watch design has received several awards.

The engine on your wrist: the Miyota 8215

The Miyota 8215 automatic movement has been produced by the renowned manufacturer Miyota since 1977. Since then, it has established itself as robust and reliable in the watch world.

A power reserve of 40 hours and a date function make the mechanical movement a reliable companion in everyday life.

Waterproof and highly elastic rubber strap

We manufacture our rubber strap with high-quality fluorocarbon rubber from a single mould.

Hard-wearing, robust and pleasant to the touch. The textured back also prevents it from sticking to the skin.

Easy strap change without tools

Thanks to the quick-change system, you can give your timepiece a new look in just 10 seconds:

1 — Slide the pin of the spring bar inwards.

2 — Pull the strap off the watch.

3 — Put on a new strap by sliding the pin inwards again and inserting the spring bar one after the other into the holes in the case.

Any questions left?

What exactly does waterproof to 20 atm mean?

The specification 1 bar usually corresponds to 1 atm or 10 m test pressure. At 20 bar, a water column of 200 metres is assumed.

The specification therefore does not refer to a real diving depth, but to the test pressure under laboratory conditions.

With a water density of 20 bar, the Marus is suitable for snorkelling, swimming and scuba diving.

How is the movement maintained?

We recommend that you have your watch serviced every 3-5 years if it is used daily.

Since there are oils and resins in the watch that can dry out over time, they should be replaced regularly, otherwise mechanical abrasion or bearing damage can occur in the movement. Seals should be checked every 5 years and replaced if necessary, crown and barrel every ten years. This ensures that you will enjoy your mechanical watch for a long time.

You can have your watch serviced directly by our watch service or by one of our specialist retail partners in your area.

Is the bezel rotatable?

Yes, you can turn the stainless steel bezel of the Marus against the Sinn watch hand.

The waffle structure on the edge of the rotating bezel makes it easy to grip and it sits firmly on the case.

By adjusting the zero mark (the triangle at 12 o'clock), divers can measure the exact duration of their dive.
